So, the director works on script a lot and even when the shoot is going on, he could be worrying about how to make it better.
As Koratala Siva has been waiting for Chiru about an year, he asked the actor to work on his fitness and reduce weight for the film.
Not trying to start immediately, he asked Chiru to take his time 2 or 3 months and get to the best shape he can by reducing the weight.
Well, Chiranjeevi took it as an ultimatum from his director and started working on it. He is maintaining a diet, going to a gym and at the age of 64, we could see him dancing and romancing on screen in his next after Sye Raa!
